The main difference between these mattresses is the materials. The GhostBed offers extra bounce and cooling with their latex layer.

Both mattresses prioritize cooling technology and the contouring benefits of memory foam. You’ll notice that the different materials used result in a slightly different feel between the two.
Because both beds land at medium-firm, the main difference in their construction starts with GhostBed’s latex make-up and Casper’s all-foam design. The Ghostbed uses four layers of latex and gel memory foam to offer premium cooling technology and responsiveness. While this combination works great for cooling and appeasing hot sleepers, it’s not the best for providing targeted pressure relief or motion isolation.
The Casper utilizes its three soft foam layers to provide incredible pressure relief, spine alignment, and motion transfer. Its zoned support layer is ideal for back and side sleepers, because it evenly disperses your body weight while still cushioning your hips and shoulders.
If I had to pick between the two, I’d go with the GhostBed for the cooling properties, but that’s because I’m a hot sleeper. The Casper works for all sleep positions, and cradles your pressure points. They both have a soft, yet supportive feel, so your choice will be based off of your own unique preferences and needs.
Composed of four layers, the GhostBed uses both latex and gel memory foam to provide optimal responsiveness, even support, and cooling.
The Casper features three soft foam layers that offer zoned support and pressure relief. This is a bed that will cradle your pressure points, and give you that huggable feeling characteristic of memory foam.
Our evaluation breaks down each mattress’s strengths and weak spots. Take a look to learn why Casper beat out GhostBed in the final score.
|Motion Transfer Test||7.5||8|
|Edge Support Test||8.5||9.5|

Let’s dig deeper into some of the main differences in score, so you can get a better idea of why the Casper beat out the GhostBed in our testing.
While the Casper did have the higher score in edge support, the GhostBed also performed well. Edge support deals with how secure and sturdy the borders of the mattress are, so if you happen to roll to the side or frequent the edge of your bed, you won’t fall off.
You really can’t go wrong with either the Casper or the GhostBed when it comes to edge support, but if you’re extra paranoid about sliding off in the middle of the night, go with the Casper, which has the higher score by a solid point.
Motion transfer, or motion isolation, defines how well a mattress isolates motion. This is an especially important factor for couples or those who sleep with a pet as the more a mattress limits motion transfer, the less you will feel the movements of your partner or pet.
It’s no surprise here that the Casper outperformed the GhostBed in motion transfer. This can be accredited to the Casper’s all-foam design, which excels in isolating motion. So for couples, we’d recommend the Casper for uninterrupted sleep.
Spine alignment is a measure of how well a mattress keeps your spine straight, or in a neutral position, while you rest. Our testers were so impressed with the Casper’s ability to maintain spine alignment that they almost gave it a perfect score! The GhostBed was lacking rather significantly in this area, only earning a 7.5 out of 10. Spine alignment is important no matter the sleep position you enjoy most, but if you’re a back or side sleeper especially, the Casper would be the better pick.
A mattress’s trial period refers to the length of time the company gives you to test out the mattress. Should you decide the bed isn’t for you, you can return the mattress for free during the trial.
Both the GhostBed and the Casper scored well for their trial periods. The GhostBed scored a point higher, and has a 101 night trial, while the Casper has a 100 night sleep trial. Either way, you have ample time to try out the mattress and decide if it’s a good fit for you.
If we’re going by the numbers, Casper outranks GhostBed in the total score and several individual categories; however, the GhostBed has many strengths to spotlight. When deciding between the two, consider your sleep style, cooling, and buying experience.
Both mattresses in this comparison are medium-firm, meaning they’re about right in the middle, which works for all sleep styles. Some consumers call medium-firm the “Goldilock’s” level of firmness, meaning it’s not too hard and not too soft. Generally, medium-firm mattresses provide enough support for back and stomach sleepers and enough cushion for side sleepers.
In this case, we recommend the Casper for side sleepers. It received an 8.5/10 on pressure point relief, compared to GhostBed’s average 6.5/10. Pressure relief is extra important for those putting weight on their shoulders and hips. Casper also received a 9.5/10 on spinal alignment, while GhostBed earned 7.5/10. Side sleeping has the potential to cause extra strain on the spine, so staying aligned through the night helps to prevent back pain.
Both beds are great choices for stomach and back sleepers because these positions need a firmer feel. Stomach sleepers especially need to avoid sinking into their bed, which can increase contortion of their neck and spine. The GhostBed and Casper each offer denser supportive layers and cushioning comfort layers. Finally, combination sleepers will probably want to opt for the Casper, since many combination sleepers end up on their side at least once during the night.
While the GhostBed and Casper both spotlight their cooling technologies, GhostBed earned a higher score on our cooling evaluation with an 8.5/10. That means our testers thought it helped regulate their temperatures a little better than the Casper. The Casper earned 7/10, meaning it offers average temperature regulation.
For these reasons, we recommend the GhostBed for sleepers who run hot. This can also include couples, whose dual body heat tends to amplify the overall temperature beneath the sheets. The scores are relatively close, so you get at least some cooling with either mattress choice.
Buying experience can make the difference between being stuck with a bed you don’t love and finding the exact right fit for you. Both Casper and GhostBed improve their shopper’s buying experience by offering sleep trials, free shipping, free returns, and optional set-up services.
Casper ships your new mattress for free within 1-2 days of ordering. UPS typically delivers your mattress within 2-7 business days. They give you 100 days to trial your new bed, but ask that you allow 30 days before requesting a free return and full refund. They also offer in-home delivery and set-up for $100 (excluding Alaska and Hawaii) and $75 in Los Angeles or New York City. For an extra $50, they’ll remove and dispose of your old mattress, as well.
GhostBed outdoes Casper’s sleep trial by a single day. You get 101 days to test your new mattress. Their shipping is also a bit quicker than Casper’s,you can have your GhostBed mattress in 3-5 days with free shipping. They also offer in-home set-up and old mattress removal for $199.
Lastly, both mattresses were fairly easy to unbox. The Casper took around 4 hours to fully inflate and there was mild off-gassing, but it was gone after a few hours. The GhostBed only took 2 minutes to set up. There was also some off-gassing that dissipated within a few hours. We recommend airing out the room where you set up your new mattress until any scents are gone before putting on your sheets.
